Ok my search future is acting up for some dumb reason. My question is, does anyone that owns a Bullitt or a Cobra running the 13in brakes, know the backspacing that will clear the factory calipers when using a set of front drag wheels. I will be using a 15 inch front wheel. I really don't want to have to run spacers to clear the calipers, kind of an uneasy feeling. Thanks in advance.
